Problem

Two spherical stars

A

and

B

emit blackbody radiation. The radius of

A

is 400 times that of

B

and

A

emits

10^4

times the power emitted from

B

. The ratio

\left(\dfrac{\lambda_A}{\lambda_B}\right)

of their wavelengths

\lambda_A

and

\lambda_B

at which the peaks occur in their respective radiation curves is
